If it's got an electrical problem such that it's trying to play a SP tape at LP or EP that could account for what you describe. I've seen decks do that before. I typically junk decks when they get that bad if they aren't anything special especially the newer ones that do everything in 2-3 chips.

I'm not sure, the VCR in question has a switch on it that can go through SP, LP and SLP but I don't see anything on the VCR that tells me what speed its playing at (that I can see of) I do know that I tried several tapes on it and it did the same thing on all of the tapes I tried out.
The tapes I used to try out the VCR were all tapes that were around 50 minutes or longer up to about 110 minutes or so so I don't know if that says anything about the speed the tapes were recorded at or not, but the boxes that held the tapes didn't say what speed they were recorded at.
The VCRs that are the subject of this thread I think would be worth trying to fix because they are both 4-head VCRs and at that they are very early 4-Head VCRs.
Plus I've always wanted a top-loading VCR with a wired remote to monkey around with because I went to a church daycare when I was a kid that had some of these types of VCRs and always remembering how much of an interesting thing they were because I had up to that point only ever seen front-load VCRs but never a top-loader and that was what kind of got me interested in old electronics.
Also they are very solidly built units and they have several boards inside for controlling everything instead of having things all on one or two chips like the more modern VCRs did, and also they have nice big Linear Power Supplies instead of Switchmode Power Supplies which make them nice units to work on.
Anyways is there anyway to figure out what speed the VCR is playing at or what speed a tape is recorded at when the VCR doesn't show a playback speed or a tape doesn't say what speed it was recorded at?
